Why is my iCloud password not recognized on my MacBook?
MacBook (13-inch, Aluminum, Late 2008) OS X El Capitan Version 10.11.6
processor 2Ghz Intel Core 2 Duo
Memory 8GB 1067 Mhz DDR3
Im having issues logging into the iCloud on MacBook after the Password is not being recognized.
The Password for iCloud was changed on iPhone 8Plus after errors started on the MacBook.
Ive tried all the Passwords in my Register book, and the changed Password on iPhone for iCloud… to no avail…
Please advise best course of action to proceed?
